Don and Marion Caulkins have served in Brazil since 1985 with MTW and the Navigators. They moved into the mega-city of São Paulo more than five years ago to minister God’s redeeming love to the lost. While most people move away from the traffic, noise and pollution of a city inhabited by 19 million people, the Caulkins see a unique opportunity to live in the most important city in all of South America.

In order to further the ministry of the Navigators in the city and expand his sphere of influence for Christ, Don has enrolled in the University of São Paulo. He has found an openness to share spiritual truths with all four years of students and continues to build relationships with professors at the university. Don and Marion are also ministering in their community to couples and professionals who live in the western neighborhoods of São Paulo. Through Bible studies and individual discipleship time, several couples have professed Christ and seen the Lord at work in their marriage and parenting styles.
